Searching a listBox for a specified string VB6 - search

Question

I have a listbox called lstSerial and a textbox called txtSerials. What I want to do is search lstSerial for the string that's entered in txtSerials. I'm using VB6 in Microsoft Visual Basic 6.0, and I'm having a terrible time finding documentation.
Thanks.

#AlexK's answer is technically correct - yes - it will work, but it's not the preferred way to go. There is an API call for this very purpose:
Private Declare Function SendMessage Lib "USER32" Alias "SendMessageA" _
(ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As _
Integer, ByVal lParam As Any) As Long
'constants for searching the ListBox
Private Const LB_FINDSTRINGEXACT = &H1A2
Private Const LB_FINDSTRING = &H18F
'function to get find an item in the Listbox
Public Function GetListBoxIndex(hWnd As Long, SearchKey As String, Optional FindExactMatch As Boolean = True) As Long
If FindExactMatch Then
GetListBoxIndex = SendMessage(hWnd, LB_FINDSTRINGEXACT, -1, ByVal SearchKey)
Else
GetListBoxIndex = SendMessage(hWnd, LB_FINDSTRING, -1, ByVal SearchKey)
End If
End Function
So you want to do this:
lstSerial.ListIndex = GetListBoxIndex(lstSerial.hWnd, txtSerials.Text)

dim find as string,i as long,found as boolean
find=txtSerials.text
for i=0 to lstserial.listcount - 1
if strcomp(find, lstSerial.list(i), vbTextcompare)=0 then
found = true
lstSerial.setfocus
lstSerial.listindex= i
exit for
end if
next
if not found then msgbox "not found ..."
